A disposable incontinence detection system monitors an area for incontinence events. The incontinence detection system includes a substrate having a length and a width defining a monitoring area. Additionally, the incontinence detection system includes a moisture sensor positioned within the monitoring area. The moisture sensor includes a circuit that includes traces spaced apart from each other such that the presence of moisture bridging a space between at least two of the traces will close the circuit. Additionally, the circuit includes a removable conductor coupled to one of the traces such that removal of the conductor irreversibly prevents the trace from closing the circuit. The moisture sensor is configured to determine whether the circuit has been closed.
